Product Description

SkyTech CLS-CCD filters are suitable for modified Canon DSLR's because they block UV and IR light, which are normally blocked by the built-in filters in the camera. This gives sharper stars. This version is for modified EOS cameras. Clips in front of the sensor alowing lenses or T rings to fit to.The SkyTech CLS-CCD (City Light Suppression) filter is designed to improve the visibility of various deepsky objects by blocking light pollution, while allowing light from deepsky objects through. Solves the problem where many telescope adapters are not suitable for filters and protects your expensive camera chip from dust.

How does it fit the camera?
The filter is designed to simply clip directly in front of the sensor and is easily removable, still allowing lenses or adapters to work, also protecting the sensor from dust. Click the main product image to see how it fits in.

SkyTech CLS-CCD filters are suitable for modified Canon DSLRs because they block UV and IR light, which are normally blocked by the standard built-in filters in the camera. This gives sharper stars on your images.

The CLS-CCD filter has a wider pass-band than a UHC filter, so it gives a more natural colour results than a UHC filter. CLS is therefore best for mild to moderate light pollution on city outskirts or suburban locations.

Compatible with all APS-C sized Canon EOS cameras. Not for full frame cameras. Do not use with EFS lenses because the rear elements can strike the filter. This is not an issue with most Sigma and 3rd party EF-S lenses and of course telescopes.

Why choose a SkyTech Clip-Filter?
It can be inserted or removed in seconds. All lens functions (focus, preview screen, image stabilization) work as usual.
If you have a telescope with short space between reducer/flattener and camera and filter wheel, a clip filter is the solution.
It protects your sensor from dust build-up during long exposures.

How this filter works: Artificial lighting such as mercury vapour lamps, both high & low pressure sodium vapour lights and unwanted natural light caused by neutral oxygen emission in our atmosphere (skyglow) are almost completely suppressed by the SkyTech CLS filter.

The filter selectively allows light from deepsky objects through, with high transmission of ionised oxygen O-III (496nm & 500nm), Hydrogen Beta / N-beta (486nm), N-II(654nm and 658nm), H-alpha(656nm) and S-II(672nm). (Additionally the "CCD" version blocks UV (ultraviolet) and IR (infrared) light giving sharper stars.

By selectively blocking light pollution and transmitting these desirable wavelengths, the contrast and detail of deepsky objects is greatly enhanced.

Technical Data:
Schott glass substrate material with precision polish.
Glass thickness 1.0 mm.
Surface Quality: 60/40 (Refer to MIL-O-13830)
Fine-optically polished to ensure accurate 1/4 wavefront and < 30 sec parallelism over both surfaces
95% transmission of main nebula emission lines (i.e. Ha 656nm, OIII 496nm & 500nm, SII 672nm and H-beta 486nm).
0.1% transmission of off-band, specifically the major emission lines of artificial light pollution (i.e. Na 589nm, Hg 435nm and 578nm).

Dichroic Filter Coatings:
Multi-layer anti-reflection coating (AR Coat). Additional UV IR Blocking layer.
Special high homogeneity coating process with electron-beam gun evaporation and Ion-assisted deposition coating technology for durability and resistance to scratching, as well as stability on CWL (central wavelength) no deviation with temperature change.

SkyTech EOS Clip filters fit the following Canon EOS APS-C cameras:
7D MkII, 7D, 20D, 20Da, 30D, 40D, 50D, 60D, 60Da, 70D, 77D, 80D, 90D, 300D, 350D, 400D, 450D, 550D, 600D, 650D, 700D, 750D, 760D, 800D, 1000D, 1100D, 1200D, 1300D, 2000D, 4000D, 100D, 200D

Customer Reviews

10/10  Great Filter  I have had the full spectrum modification done on my Canon 800D, and this filter has made the difference from taking ok pictures of the nebulas and stars, to taking great pictures. Great price and filter arrived packaged well and in good time. I would definitely recommend Harrison Telescopes to you  (25/07/2021) Trevor Tear - Heybridge


10/10  Very prompt service!    (12/03/2021) -


10/10  Easy to fit  I got this to use with my modified dslr & it arrived the next day. Excellent service. I just wish the uk weather could provide as good a service. Impatiently waiting for clear sky’s.  (21/02/2021) - Kent


8/10  works well, had to adjust to fit  I had a bit of work to do with a screw driver to gently open out the springs as the filter was initially loose in the camera (Canon EOS 250D). No positive clip in place. Once I had done this it fitted okay and now works fine.  (30/12/2020) Neil - Reading
Our Reply: These are adjustable to fit the slight variations in the Canon cameras, if you click the picture on the product page it shows how to do this very easily.


10/10  Excellent purchase and service  Bought this recently for my setup.. I live in a heavily light polluted area.. Only had a clear sky for a few hours since but this makes a great deal of difference to captures.. Efficient service  (05/12/2020) - London


10/10  Superb   Shooting from my back Garden 2 miles away from Manchester, the CLS-CCD clip in filter is the perfect solution for me. It eliminates virtually all the unwanted street light wavelengths leaving me with great file to work with. Great buy really pleased.  (23/05/2020) Martin - Manchester


10/10  A very nice quality filter.  Looks a very nice quality filter, not had a chance to use it yet but other online reviews are all good regarding performance. A great service from Harrisons - immediate reply to any enquiries and very helpful advice. Very satisfied and will be using them again for future purchases. Thanks Ed.  (18/04/2020) Andrew Hatfield - Bradford


10/10  Canon clip in filter  Very fast delivery as always with Harrison Telescopes. The filter needs to be slightly adjusted to get a good fit in the camera and once completed holds securely. Very pleasing results on the very first use imaging the orion nebula and my first clear image of the Horsehead Nebula   (01/03/2020) Andrew Green - North Walsham
